Detailed description of the invention

Forward now each figure to describe example embodiments of the present invention, wherein in all several views, similar numbering and/or mark represent similar components.For simplicity, only some elements in the same group of available numbering mark.Graphic object is to describe example embodiments and not for making object.Therefore, the feature shown in each figure only for illustrating object and may not drawing in proportion, and to its selection is only for convenience and the object clearly stated.

The present invention relates to a kind of pretreatment system for hardboard, wherein pretreatment can comprise the processing of any type, such as, form folding line, local cut channel, complete cut channel, embossing etc.Process by cutting equipment (such as cutter chi mould and bed die), laser equipment (such as producing the lasing light emitter of laser beam) etc.Key factor when carrying out pretreatment and especially when disposed material is corrugated boxboard is the thickness of hardboard.

The laser system used in some embodiments of the invention for using laser energy to cut material, partial cut, perforation, mark or otherwise process.Laser is by energy is processed material by the horizontal delivery be enough to material processes in material.The amount of energy depends on various factors, comprises the time of lasing light emitter intensity and laser irradiation material.For example, the described time can be determined by cutting speed (that is, the laser facula irradiating material surface is crossing speed at that time).Usually by setting laser intensity and cross the amount that speed (laser facula crosses the speed of treated material) controls the energy by being delivered to treated material, laser intensity and cross speed jointly setting process speed.Optionally, also other factors can be taken into account.If laser beam is not focused on material surface rightly, then will become comparatively greatly through irradiated area on material, therefore can reduce laser intensity (it is determined divided by through irradiated area according to energy), and can need slower processing speed.But if process velocity (such as cutting speed) was slow for institute's energy requirement delivering amount, then material can overheat, thus damage is caused to the material near process path (such as line of cut).This damage may present perhaps various ways (brown near such as line of cut or black burn trace), and in the field of businessly known with many titles, such as, and heat affected area (HAZ).When processing speed appropriate (such as, just reach required effect and no longer stop, therefore avoid making the material near process path overheated), described damage can be minimized.

Typically be focused and provide the laser beam being enough to carry out hardboard the energy density of pretreatment (such as forming complete cut channel or local cut channel) to have limited depth of focus.Depth of focus is focus (that is, the point that in beam axis, the diameter of laser beam is minimum) and along the approximate twice of beam axis beam diameter even as big as making energy density be reduced to the distance between the point of the level of needs such as slower processing speed.Therefore, depth of focus is defined as the length maintaining evenly process velocity (such as can not slow to less than 1/1.2) haply along laser beam path.Described distance is normally around focus near symmetrical.Depth of focus depends on many factors, comprises particular optical and arranges, such as F number and operating distance; Laser beam wavelength; Laser energy levels and intensity; Etc..For example, the CO from 10.6 micron wave lengths is being used ₂during the laser beam of lasing light emitter and the specific hardboard cutting with particular optical device are arranged, depth of focus is that 1.5mm is long, and wherein pinpointed focus obtains in approximate middle.

If the material that will process (such as, will cut) has comparatively heavy thickness (such as, thick than the depth of focus of specific setting), then may there is the not desirable situation that wherein required process velocity changes along depth of material.Pinpointed focus place and the focal depth area around it (such as, when hardboard is horizontal above pinpointed focus and below be still in region within depth of focus distance) place, process velocity may be faster than the region place outside depth of focus.In such cases, in order to realize processing completely, process velocity can be set as be worth more slowly.But in the case, the volume be in around process line (such as line of cut) inside the region within depth of focus may be affected by HAZ due to excessively slow process velocity.

In order to solve described problem, can use more light laser source, this may cause HAZ near treated line.In another replacement scheme, laser beam can be suitable for crossing twice, treated line or more time to guarantee to form complete cut channel.But the method significantly reduces the treating capacity for the treatment of system and can increase cost, this is because each hardboard must experience longer operation.In yet another alternative, the speed of carrying out needed for pretreatment to hardboard can be reduced.In all these replacement schemes, hardboard is thicker, processing time, Time To Market are longer, and the power requirement of laser instrument or other subsystems, the cost of required mechanical device, operating cost or other parameters are higher, can reduce the parameters such as such as cut channel quality simultaneously.In general, hardboard is thicker, and carrying out time needed for pretreatment, power or other resources to it may be more.

Solution described in the present invention relates to system to be modified as and in prefabrication, not only needs folding line part but also form folding line in needs cut channel part.The operation forming folding line can make hardboard flatten or thinning in described position, and this is especially remarkable in corrugated boxboard.After making corrugated boxboard thinning, when such as processing (such as cutting) hardboard by laser beam after a while, laser beam can focus on along the full depth of hardboard, is constrained in depth of focus this is because the thickness of hardboard is reduced to.This can produce complete and cut channel accurately, and near treated line, there will not be HAZ, and do not need to slow down processing speed or carry out extra all over time.

In some machines, in computerization file (such as in DXF form), indicate shape and the position of required folding line and cut channel.

In some machines, form folding line by the cutter chi mould with polymer line or the region being in required folding line shape and position above.By forming cutter chi (often criticizing hardboard once) with under type: make nozzle at over-injected polymer such as plane, cylinder, cylinders, make material cured (if needs) afterwards.For example, this operation can be performed as described in WO2011/145092 International Patent Publication case.By according to the shape of required cut channel and position and the laser beam launched forms cut channel.Therefore, described operation also can be suitable for the shape of required cut channel and position to form folding line, and make when hardboard arrives cutting module, it has been with folding line and therefore in process position thinning, has made process become comparatively effective, as mentioned above.Hardboard can be made to form folding line through the full depth of hardboard and/or the part extending only through its thickness through pretreatment folding line.Exemplary scope can be the 20%-60% of hardboard thickness.

To understand, and form folding line in needs cut channel part and not only can use together with laser cutting, and can use together with another kind of cutting method (such as being cut with bed die by cutter chi mould).Also will understand, and add folding line in cut channel position and also can be applicable to other sheet materials, such as corrugation plastics or hollow sheeting.
